Ok I have done my due diligence on research and found the following fixes that helped out tremendously, but its still broke as all ****. My first problem was "mouse lag", I was able to fix this by turning off the vertical sync by adding the following line to my ini file: iPresentInterval=0 My second problem was "mouse stuttering", I was able to fix this by turning off Mouse Smoothing or Acceleration by changing the following line in my ini file: bMouseAcceleration=0 My third problem is the infamous "Y axis sensitivity", Everyone recommends adding the following change to the ini file: fMouseHeadingYScale=0.0200 fMouseHeadingXScale=0.0200 They then recommending lowering (yes this seems backwards) the fMouseHeadingYScale until it fixes the Y axis sensitivity. Some of the numbers I have seen are fMouseHeadingYScale=0.0140 or fMouseHeadingYScale=0.0100 I kept tweaking the YScale down and it seemed to get better to a point, but now no matter how long I make the Y scale it doesn't help, here are my current settings: fMouseHeadingYScale=0.00005 fMouseHeadingXScale=0.0200 Any help is greatly appreciated, my game is unplayable at this point and Bethesda hasn't responded to my plea for help.
